WINDOW-SCREEN.

Specification of Letters Patent.

Patented Nov. 7, 1916.

To all whom it may concern Be it known that we, CHAUNCEY A. Barns andWALTER W. HOBBY, citizens of the United States, residing at WhitePlains, in the county of lVestchester and State of New York, haveinvented new and useful Improvements in lVindow-Screens, of which thefollowing is a specification.

This invention relates to improvements in window screens and hasparticular reference to that class known as extensible screens.

The invention aims to provide a device of the above mentioned character,capable of self-adjustment to accommodate windows of varying widths, thescreen being designed for vertical sliding adjustment upon the blindstop of a window and to retain itself in any desired position, wherebythe manipulation of the upper and lower window sashes is provided forwithout any interference on the part of the screen.

Other objects will appear as the nature of the invention is betterunderstood, the same residing in the construction, combination andarrangement of parts hereinafter more fully described.

In the drawing forming part of this application like numerals ofreference indicate similar parts in the several views, and whereinFigure 1 is an elevation of the outer side of the screen showing thesame in applied position. Fig. 2 is an elevation of the other side ofthe screen removed from the window. Fig, 3 is a sectional view taken online (0-64 of Fig. 2. Fig. 41 is a sectional view taken on line b-?) ofFig. 2.

A screen constructed in accordance with our invention comprising a mainframe section 5, and laterally adjustable auxiliary side sections 6. Theframe in its entirety may be constructed from any suitable material,preferably metal, the main section 5 being formed to provide upper andlower horizontal flanges 7, the latter in addition to forming guides tobe received by the grooves 8 in'the auxiliary sections 6, are adapted tobe grasped to raise or lower the screen when desired. The main sectionis provided with an enlarged central opening,

the edges of which are bent upon themselves to form the strips 9 beneathwhich the marginal edges of the wire fabric 10 are arranged and clampedin the manner shown.

The auxiliary sections 6 are mounted to s de p n t e Peter are c t emain tion 5 and have rearwardly projecting lugs 11 extending throughelongated slots 12 in the side portions of the main frame 5, the lugsbeing provided with notches 13 which receive the free ends of a bowedspring 14, the latter operating to normally maintain the auxiliarysections 6 in extended position. The intermediate portions of the bowedsprings 14 are secured to the main frame 5 in any suitable manner. Theouter edges of the auxiliary sections 6 are formed to provide guidegrooves 15 adapted to receive the blind stops or beads 17 on the window,whereby the screen may be adjusted vertically, and by reason of thesliding adjustment of the sections 6 and their tendency to normallyassume an extended position under the influence of the bowed spring 1 1,it will be manifest that the screen will hold itself in any desiredadjusted position. It will be further noted that the mounting of thescreen is such that the upper and lower window sashes may be raised orlowered when desired without any interference on part of the screen. Thelugs 11 are adapted to engage the end walls of the slots 12 upon themaximum adjustment of the auxiliary sections 6 thereby preventing anycasual separation between the parts. The construc tion of the screen issuch that it will accom modate itself to windows of varying widths. Theinner edge of the auxiliary sections 6 are formed to provide the flanges18 adapted to be grasped for moving the sections inwardly toward eachother when it is desired to remove the screen from the window. Thescreen is extremely simple in construction, thereby reducing the cost ofmanufacture to a minimum, and one which is very efficient in use.

It is believed that from the foregoing description the nature andadvantages of the invention will be thoroughly understood withoutrequiring a more extended explanation and therefore the same has beenomitted. However we desire to have it understood that various changes inthe construction, and proportions of the various parts may be resortedto when desired as fall within the scope of the appended claims, withoutdeparting from the spirit of the invention.

What is claimed is 1. A window screen mounted for sliding adjustment andcomprising a main frame and late a y adju table side sectiQH m ans.

for normally extending said sections, means for limiting the outwardmovement thereof, and the inner edge section forming a flange adapted tobe grasped for moving the sec- I tions toward each other.

2. A window screen mounted for sliding adjustment and comprising a mainframe and laterally adjustable side sections, spaced upper and lowerhorizontal flanges on said main frame, said sections being formed withgrooves for the reception of said flanges, means for normally extendingsaid sections, and means for limiting the outward movement thereof.

3. A window screen mounted for sliding adjustment, comprising a mainframe and laterally adjustable side sections, lugs projecting from eachof said sections through elongated slots in the main frame and slidablymounted therein, and a bowed spring 20 secured to the opposite sides ofthe main frame engaging said lugs to normally main tain said sections inextended position.

In testimony whereof we affix our signatures in presence of twowitnesses.
